摘要: Dextran-T500分离人血白细胞,反复冻融破坏细胞,丙酮抽提白细胞血管紧张素Ⅱ样物质(LATⅡ-LM),高效液相层析(HP LC)进一步分离纯化LATⅡ-LM.LATⅡ-LM与氚标记血管紧张素Ⅱ(3H-ATⅡ)具有同样HPLC保留时间,经特异抗ATⅡ血清测定,LATⅡ-LM具有免疫活性,兔颈动脉条收缩试验证实LATⅡ-LM具有血管收缩活性。

Abstract: Separation of the human Leucocytes by Dextran-T500. Breaking the cells by freege and thaw. Extracting the LATⅡ-LM by acetone. Purifing the LATⅡ-LM by HPLC. The LATⅡ-LM has the same HPLC (Reversed phase) retention time with~3H-ATⅡ, has the immunoractivity of ATⅡ and the va-scular contractive activity.

Key words: leucocyte, angiotensinⅡ, HPLC
